説明

A 46-year-old man with NIDDM and pulmonary tuberculosis was admitted to our hospital because of generalized fatigue and cough. As glycemic control was poor, treatment with mixture injections of short-acting and intermediate-acting insulins twice a day was begun. After treatment with these preparations for two months, he noticed local, itchy, wheal-and-flare reactions at the sites of injection, indicative of an insulin allergy.<BR>Human insulin-specific bound IgE was positive and insulin antibody formation was elevated to 89.8%(≤10%). Intradermal testing for insulin allergy was performed with founteen commercially available preparations of human, porcine and bovine insulins. All short-acting and intermediate-acting insulins produced allergic reactions, whereas none of the long-acting insulins was allergenic. These long-acting insulins were monoclinic insulin crystals. when decrystallized by lowering the pH from 7.0 to 3.0, even these insulins induced a positive reaction. The findings indicate that, in this case, the monoclinic crystallized structure of human insulin may have masked the antigenicity by which the short-and intermediate-acting insulins induced allergic reactions.
